Degradation in a Thermal Barrier Coating [PDF]

Advanced Ceramic Materials, 1987
The failure of a thermal barrier coating involves cracking and spalling of the ceramic layer, primarily brought about by bond-coat oxidation during operation. The present investigation focuses on the microstructural and microchemical changes in a thermal barrier coating, oxidized in air for 1 and 10 h at 900{degree}C.

Erosion of Ceramic Thermal Barrier Coatings [PDF]

CORROSION 1984, 1984
Abstract A study has been made to relate the erosion behavior of several experimental zirconia-base ceramic thermal barrier coatings to their processing parameters and microstructure. The incremental erosion rates were measured and each specimen was examined using optica and scanning electron microscopy.
